Terminal Management

Connect

connect Method

Connects to a payment terminal. Whenever the connection to the device is lost, the SDK will keep on trying to establish a connection until it’s re-established. No special actions are needed.

Parameters

Parameter	Notes
device Required Device	This parameter specifies which device type you want to connect to.

Code example

//Connect to a device
Device device = new Device("CardReader7", "08:00:69:02:01:FC", "1", ConnectionMethod.BLUETOOTH);
Device device = new Device("LocalDevice", "0821032398-PAXA920", "", ConnectionMethod.ANDROID_PAYMENT);
Device device = new Device("CloudDevice", "0821032398-PAXA920", "", ConnectionMethod.CLOUD);
api.connect(device);

Events invoked

connectionStatusChanged

Each time the card reader state changes (ex : going from Connected to Disconnected) the ConnectionStatusChanged event is called. It causes the connection manager to invoke this event with the appropriate information.

Returns

Parameter	Notes
Boolean	true if the operation was successfully.

Disconnect

disconnect Method

Disconnect will stop the active connection (or reconnection process). Please note that the method ignores the current state of the payment terminal and just stops the connection. Calling disconnect might result in a commmunication error if triggered during a transaction.

Code example

//Disconnects from the payment terminal 
api.Disconnect();

Events invoked

connectionStatusChanged

Causes the connection manager to invoke this event with the appropriate information.

Returns

Parameter	Notes
Boolean	True if the operation was successful.

Get Device Manufacturer

getDeviceManufacturer Method

Code example

Manufacturer manufacturer = api.getDeviceManufacturer();

Returns

Parameter	Notes
Manufacturer	The payment terminal manufacturer.

Get EMV Report

getEMVConfiguration Method

Fetches the logs from the device and reports them to the deviceLogsReady event.

Code example

//Downloads logs from device
api.getDeviceLogs();

Events invoked

ReportResult

Invoked when the sdk has finished downloading the EMV report from the payment terminal.

Returns

Parameter	Notes
Boolean	True if the operation was successfully sent to device.

Get Paired Devices

getPairedDevices Method

Returns the payment terminals associated with the specified ConnectionMethod.

Parameters

Parameter	Notes
method Required ConnectionMethod	The type of connection with the payment terminal (Bluetooth, Cloud, etc.).

Code example

// Get paired terminals
List<Device> devices = api.getPairedDevices(ConnectionMethod.XXX);

Returns

Parameter	Notes
List<Device>	The list of payment terminals.

Get Transactions Report

getTransactionsReport Method

Fetches your transactions report from a payment terminal. If you want to print the report, you can call printReceipt with the string returned in ReportResult event as parameter.

Parameters

Parameter	Notes
reportConfiguration Required ReportConfiguration	This parameter specifies the filter to get transactions report.

Code example

//Get the transactions report for device "12345", from 30th April 2021 at 00:00:00, to 30th April 2021 at 23:59:59, in eurs:
List terminalSerialNumber = new ArrayList<>();
terminalSerialNumber.add("12345");
ReportConfiguration configuration = new ReportConfiguration("EUR", "20210430000000", "20210430235959", "+00:00", terminalSerialNumber);
api.getTransactionsReport(configuration);

Events invoked

ReportResult

The report will be returned to the registered ReportResult interface.

Returns

Parameter	Notes
Boolean	True if the command was processed successfully. False if the sending was not successful.

Flash Reset

deleteDeviceConfig Method

Sends a command to the payment terminal to delete its configuration.

Code example

api.deleteDeviceConfig();

Print Receipt

printReceipt Method

Print on demand functionality allowing the merchant to print any HTML formatted receipt. It is possible to print images or barcodes as well as passing directly a URL to the printReceipt function. A bitmap can also be printed, in order to do so it needs to be rendered as an image and inserted into the html.

tip

Receipts received in the terminal transaction result can either be a URL OR an HTML formatted receipt. The format can be changed by updating the getReceiptsAsURLs boolean when initializing the SDK Settings. Note that if the terminal is not able to upload the receipt to the Handpoint cloud servers and generate a URL then the HTML formatted receipt will be delivered to your software. It is important to be able to manage both formats.

Parameters

Parameter	Notes
receipt Required String	The receipt must match the following HTML Print Format. The Transaction Report (also called End of Day Report) can be printed from the string returned in the ReportResult event.

Code example (Prints a receipt with Handpoint logo)

//Print a receipt with Handpoint logo (bitmap format)
String validReceipt = "<html><body><img

Search Devices

searchDevices Method

Starts the search of payment terminals associated with the specified ConnectionMethod.

Parameters

Parameter	Notes
method Required ConnectionMethod	The type of connection with the payment terminal (Bluetooth, Cloud, etc.).

Events invoked

deviceDiscoveryFinished

Returns a list of payment terminals.

Set Locale

setLocale Method

Sets the SDK Locale (language). It is used to set the SDK language as well as the associated date and number formatting.

Parameters

//Sets the log level to info
api.setLogLevel(LogLevel.info);

Events invoked

None

No events are invoked.

Returns

Parameter	Notes
Boolean	True iif the operation was successfully sent to device.

Stop current transaction
